These traine members -prefa sticl'eiiedy by pktransverse members 7 and "8.

Accordingtdniy bpresent inventionll adapt ,this frame to a sheetrnetal doorby combining therewith the Aessential elements f thereof impart V@to :the door self-sustaining properl:#tiesl Toihis yend :l1-secure to itlie ftop, radial lcorner extensions and in falignnientwithgthe side xframe lnieii'ibers V2,iand.13,;right zand left handk hangers secured rigidly to and enveloping the ir-'ull cross section of these cornerk extensions .within the ivvidth yfof-the hangers,

Whicli'beingin alignment xWith the side i'ianie'membersas above vmentioned,and einbracing both ends of the top frame member, absorb the entire load which effect is contributed to by the reduction in span dueto the narrow skeleton frame relatively to the full width of the door presented when the filling or sheeting is in place. n

These hangers consist of front and back members for each hanger, right andv left front hangers and right and left back hangers being necessary. In order to provide even and corresponding front and back faces for the radial extensions each is supplemented by back faces presented by comparatively short angle irons. These short angle irons are of suflicientl length to receive the' rivets or 4bolts 10 for fastening together the bent ends 9 of the frame piece. They are indicated at 15` Figure 5 where. it will be seen that corresponding bearing faces are presented at both lfront and backof the door. The hangers proper consist of right and left front members 20 and corresponding right and left back members 22. Each of these members consists of a plate with one end bent at right angles yas at 25 to form, when assembled with their ends 25 overlapping, a

reinforced suspension member, the main length of which is secured to the radial eX- tensions of the skeleton frame by bolts 30 securely fastening the front andv back members to the flanges presented by the members 9 and 15; the members of the hangers and the members 9and 15 being provided with bolt holes for the purpose. These overlapping portions have registering holes 26 iny which the hanger-bolt 27 is pivotally connected. This hanger-bolt is a part of the usual trolley frame 28 hung from the trolley wheel 29 travelling in a rail 60 shown clearly in Figures 1, 2, 11, 12 and 14. The skeleton frame thus constructed and hung is reinforced at its bottom by a plate 35 eX- tending throughout the full vwidth. .of thel door.

The body of my improved door isy presented by sheets a() of metal, preferably corrugated galvanized iron, laid-in panels and riveted together and to the skeleton frame c as indicated in Figures 1 and 11. The tall` door, for Steamship service, illustrated in Figures 11, 12 and 13 yhas an upper portion as compared with the shorter door for railway'service illustrated in Figures 1, 2 and 3 and this upward extension has separate shorter sheets 41. In order to accommodate a window sash, vertical window frame pieces are formed by vertical angle irons 42 fastened at their top and bottoni ends'to the frame members 5 and 7.

The shorter sheets -11 are riveted at their inner side edges to the frame bars formed by the angle irons -12 Aand their outer side edges extend outwardly to present straight side edges with the outeredges of the-sheets 40. These edges form the side margins of the complete door and extend in width slightly beyond the radial extensions, these side edges being bent back upon themselves as shown at i3 in Figure 3. rlhe top of the door is completed by short pieces 45 of sheeting, riveted at their lower edgesto the top frame piece 5 and at their opposite side edges as at. 416 to the sheets 11 while their inner edges are overlapped and riveted together `as at 17. Thel frame thus produced may have a steel sash 50 with wire glass, set therein. 1 f

As shown in Figures 1 and 11 a door constructed according toniyinvention may behung fromthe overhead rail 60 with minimum strain coming upon the filling or sheeting. It is of relatively light weight and plicity of construction; while the manner of connecting the hangers permits of their width and consequently the strength of connection :being extended to meet larger and heavier doors or narrowed to suspend doors of lighter weight.

What I claim is as follows:

1. A door for the purpose set forth` consisting of a metal frame presenting radial corner projections projecting beyond the remaining metal component ofthe door;

spaced transverse bracing means connecting the vertical members; hangers rigidly secured to the top corner projections in alignnient with the side frame members and metal body members producing a door area overlapping the said corner projections to the extreme ends of the latter for the purpose of eliminating splitting action along y'thei side edges. f n

2. A. door for the purposeset forth consisting of a metal frame presenting radial corner projections; spaced transverse bracing means connecting the vertical members;l

hangers rigidly secured to the top corner radial projections in alignment `with the sidefframe members and having their lower cured 'to the top corner radial projections in f alignment with the side frame members and having their lower edges rigidly secured yalong the frame and extending from the inside thereof outwardly; and metal body members producing a door area overlapping the said corner projections to the eXtreme ends of the latter for the purpose of elimiypossesses strength and durability with simtrolley lframe and hanger-bolt united tO- gether in Operative relation7 With the hangen bolt engaging the said overlapping ends.

In testimony whereof I have signed my name tO this specification in the presence of 15k tWO Witnesses.
